Hyd roxylysyl-galactosyl-glucose (HGG) and hyd roxylysyl-galactose (HG) were isolated from normal human urine and shown to be identical with hydroxylysine glycosides (OHLG’s) whose structure had been elucidated in other laboratories. We devised a procedure for separating the OHLG’s from many other urinary constituents by preliminary fractionation on a column of Sephadex. The OHLG’s in the fract...

We hypothesized that screening for nonadherence to antihypertensive treatment using liquid chromatography-tandem mass spectrometry-based biochemical analysis of urine/serum has therapeutic applications in nonadherent hypertensive patients. A retrospective analysis of hypertensive patients attending specialist tertiary care centers was conducted in 2 European countries (United Kingdom and Czech ...

Mutations of genes encoding isocitrate dehydrogenase (IDH1 and IDH2) have been recently described in acute myeloid leukemia (AML). Serum and myeloblast samples from patients with IDH-mutant AML contain high levels of the metabolite 2-hydroxyglutarate (2-HG), a product of the altered IDH protein. In this prospective study, we sought to determine whether 2-HG can potentially serve as a noninvasiv...
